Patented Mar. 25, 1930 PATENT OFFICE CHABLESW. WILSON, OF BENTON, WASHINGTON FAUCET Application led August 4, 1927, Serial No. 210,652. Renewed November 9, 1929.

This invention relates to an improvement in faucets and particularly to a valve operating means therefor in the use of which the valve is arranged as a quick-acting valve in fboth opening and closing, requires but the minimum amount of movement in the handle to open or close the valve, and utilizes the pressure of the water as a means for maintaining the valve on its seat.

The principal object of the present invention is to provi-de a valve structure for faucets or the like including a valve barrel in which the valve is mounted for cooperation with the ground seat under the action of a spring combined with an operating rod bar rel separable from and cooperating with the valve barrel in which operating rod barrel the rod is mounted for rotation and longitudinal movement under cooperating cam parts on the rod and barrel, the rod in one movement forcing the valve from its seat and in the opposite movement permitting the valve to move to its seat under the inlluence of the spring.

A further object of the invention is the provision of the operating rod with a head serving as a valve in addition to the main valve with the parts arranged so that both valves open and close in unison to thereby provide a double security against leakage.

A further object is the mounting of the operating rod barrel so that it may be removed at will from the faucet for repair or replacement, the main valv-e remaining closed r while the operating rod barrel is removed.

The invention is illustrated in the accompanying drawings, in which :y

Figure 6 is a view of the valve rod.

The invention is here illustrated as applied to a faucet comprising a body 1 having the usual inlet section 2 threaded at 3 for connection with the water system and having the usual outlet l. The body has a central well 5 threaded at 6 throughout its length and formed at its lower end in line with the inlet 3 with an opening 7 to provide a water inlet to the well and oppositely and some distance above its lower end with an opening 8 constituting a water outlet from the well and communicating, of course, with the outlet l of the faucet.

A valve barrel 9 eXteriorly threaded at 10 for cooperation w'th the threads 6 of the well is designed to be threaded into the well until its lower end is approximately on a line with the upper edge of the opening 7. This barrel, which is of cylindrical hollow form, has its lower end formed with a valve seat 11, preferably ground, and a correspondingly ground valve 12 is arranged to cooperate with sai-d seat. A stem 13 having its upper portion reduced at 11i is integral with the valve, the upper reduced portion lbeing threaded to receive a lll-shaped yoke 15 which is threaded onto the reduced portion to bear against the shoulder formed between the reduced portion and the portion 14.

The side arms 16 of the yoke have their upper ends turned laterally at 17 and extend substantially to the inner wall of the barrel, and a spring 18 is coiled about the yoke, bearing at its lower end on the bottom of the barrel and atits upper end beneath vthe lateral portions 17 of the yoke. Thus, the valve is inliuenced to a seating position by the spring 18. A coil spring 19 is arranged about the reduced portion 1l of the valve stem, its upper end being in coincidence with the upper surfaces of the lateral extensions 17 of the yoke.

An operating rod barrel 2O is arranged for threaded connection with the threads 6 of the well 5 above the valve barrel. This operating rod barrelhas an upper portion 21 of less exterior diameter than the interior diameter of the well, an intermediate portion 22 which is exteriorly threaded for cooperation with the threads 6 of the well, and a lower reduced portion 23 forming an annular Y v26 with the upper edge ot the valve barrel and interiorly shouldered at 27 to receive a gasket 28,. Y Y

VFormed on the inner surface ofthe vopel erating rod barrel is an annular-'cam projection 29 formed with an inclined camway 30. The portion 23 of the operating rod biarf rel, which together with the well i'ioims the chamber 24, is formed with a series of openv ings 31 to establish communication between the interior of the operating rod barrel and the chamber 24, and, as will benoted from Figure 1 of the drawings, when the operating rod barrel isin place, the chamber 24 is in registry with the outlet opening 8 from the barrel, that is, with the outlet 4 ot the-faucet.

The voperating rod 32 is formed at its lower end with a head 33 adapted to seat in the reduced portion 27 at the lower end of the operating rod barrel, the head being formed to cooperate with the gasket 28, thus serving as a valve to seal the juncture when the head is in place therein. The rod 32 is formed with a camprojection 34 adapted to cooperate with the camway 30 in the barrel, the formation ofthe camway 30 and cam pro jection 34 being suoli that on a comparatively slightturning movement of the operating rod, the cams cooperate to move the rod downwardly. It is to be particularly noted that in the movement of the operating rod the head or valve 33 moves directly away from and toward the gasket 28; that is to say, there is substantially no rotative movement Vof the headV 33 on the gasket. This insures that the head cooperates with the gasketin thesame position'a't all times, avoids undue wear of the gasket and thereby insures a more water-tight connection and increased lifeof the part.

The operating Vrod is formed lat its upper end with an angular projection 40 to removably re-y ceive an o eratin(T handle 41. Y

proper position in the well and to remain in this position without removal.

In applying the parts, the valve barrel with the connected valve is screwed into the well until the Vvalve is substantially on a lineV 7 cutoii, it'being.y that the pressure i ot' the incoming water is acting freely against y the body of, the valve, tending to insure Athat vit will remainl on its seatin ua noii-leaking condition The head 33 of the operating rod s is, of course, ot a diameter to lit within the'`Y valve barrel'overlying, however, the upper'- surfaces of the lateral projections 17 of the.

It will, of course, be apparent that the operating rod barrel, while preferably threaded into operative position as shown, need not necessarily be connected directly with the faucet. For example, as illustrated in Figure 1i, the barrel may constitute an unthreaded member having a diameter to more or less snugly fit in the well, also unthreaded throughout its upper portion, this operating barrel beingmerely placed in position and held in operative relation for the subsequent action of the parts by the closing cap 36.

What I claim to be new is:

A valve operating means for faucets, including a body having a vertical well therein and formed with inlet and outlet openings to the well, the wall of said well being threaded, a valve barrel eXteriorly threaded and adapted to be positioned in the well, a shoulder formed on the valve barrel providing a stop for said barrel, a valve seat formed at the lower end of the valve barrel, a valve seating on said valve seat, a valve stem integral with the valve extending upwards into said barrel,

said stem being reduced and threaded in its "i upper portion, a U-shaped yoke carried on the valve stem, the reduced portion providing a shoulder upon which the bend of the yoke rests, the side arms of said yoke being bent laterally adjacent their extremities, a coil spring bearing against the bottom of the valve barrel and the bent ends of the yoke, a second coil spring positioned over the reduced portion of the valve stem, a shoulder formed interiorly of the valve barrel above the yoke, a gasket seated in said shoulder, a cam operating rod adapted for movement within the valve barrel and formed with a head adapted to seat on the gasket, said head also bearing against the second spring and bent yoke arm, whereby movement of the operating rod unseats the head from the gasket, depresses the yoke which unseats the Valve opening the inlet, the second spring preventing chattering of the operating rod.

In testimony whereof I aliiX my signature.
